Koetsu vs Dynavector


I am looking at new (well new to me anyway) cartridges for my turntable. I have found a couple of interesting candidates but given that cartridges are one of the hardest things to purchase because of the problems of arranging home trials, I am interested in other peoples opinions. I am looking at the Koetsu Urushi's (either a Vermillion or a Black) or a Dynavector Te Kaitora Rua or XV1. I realize there is a bit of a price spread at normal retail but there are some demo issues that level the field a bit. My system is as follows Oracle Delphi MkIV with a highly modified Rega arm running into a modified Mod Squad Phono Drive. This all runs into a Sonic Euphoria Transformer based volume control. The amp is a custom tube amp based on the 6L6 tube (using NOS Tung Sol 5881 at the moment). This puts out twenty watts of PP power to a pair of Quad ESL 63. The cables are a mix of Homegrown Audio silver interconnects with Eichman silver RCA jacks and Analysis Audio Silver speaker cables.
My musical preferences lie in the smaller scale more introspective sphere on this system (I have a Altec Lansing based horn setup for rocking out). Anything from Frank and Ella to Johhny Cash to Bob Dylan to Dianna Krall. I also love the instruments that share the vocal sound. I gravitate to cello, saxophone and trombone over guitar and piano. I want to here the tone and texture of the voice as my first priority and timing a bit further down the line. My listening room is a bit on the large side (30' x 50' x 25') and has a very live acoustic. It has polished concrete floors and 115 year old plaster walls (I live in an 1893 Methodist church).
I welcome any opinions but I am mostly looking for people with actual hands on experience with either the Koetsus or the Dynavectors.

Thanks

Am I missing something or did a post get deleted or something? It seems like the respondents are being very reasonable and honest in their descriptions? It would seem that this type of feedback is what one would hope for when conducting research.
Dan, with the threads posted here and and AA, I believe the Urushi fit in well with your taste and requirement.

I have the old Urushi (retipped by Koetsu Japan) and have to agree with Halco its highs roll off a bit. I think it will be good enough with your speaker. I buy Urushi simply because of its lushness in mid range, other area of deficiency is less important to me. If you are looking for a cartridge with good balance frequency spectrum, don't try Urushi.
Dear Djeickme75 : IMHO there are some subjects here that we have to take in count to make a cartridge choice ( btw, I agree with Halcro that the XV-1 and Urushis are different even between the Koetsus. )

While the Urushi Vermillion is a very low output at 0.2mv the Urushi Black is 0.4mv: big difference here. While the Koetsus are low compliance cartridges ( 5cu ) the XV-1 are a medium one ( 10 cu ) and with an output between the Koetsus ( 0.33mv. ).

All these cartridge facts/specs tell us that we have to take care to match either cartridge with the right tonearm and with the right top quality phono stage too, these two " considerations " are a must to achieve the real top quality performance on each cartridge.

You say that own a modified Rega tonearm and a modified Mod Squad phono stage that for me tell us almost nothing to give you a more precise advise about.

These cartridges are not a " cheap " ones ( over 4K ) and if your Rega/Mod Squad are not up to the task ( that maybe are not, I can't be sure. ) then IMHO you are only " loosing " your time and money on the subject and maybe you can't achieve what you are looking for.

Btw you can achieve what you want with either of those cartridges with the right equipment ( synergy ) and set up.

Dan, btw which cartridge do you own/use?

Regards and enjoy the music.

I have used neither of these cartridges despite being, as a VPI dealer, able to get the Dynavector at a favorable price. I have used some of their predecessors and can agree that they are going to sound quite different. Also the room and characteristics of the system will have a large effect which is hard to predict. If I ever fell on my head and as a result was willing to spend big bucks on a cartridge I would get a Koetsu Red, but then I use transistors; so the Dynavector might well be the better choice with your tube system if you follow the principal that you balance rather than reinforce the rest of the system with the cartridge.
